UNITED FLASH LIGHT FOR DOORS.

Application led May 27, 1925. Serial No. 33,132.

rlhis invention relates generally to the use of flash lights for the purpose of locating key holes in door locks and for the selection of the proper key for the lock, and particularly to a special form of flash light adapted to be mounted on a doore The first object of the invention is to provide an exceedingly simple and efcient form of flash light designed to facilitate the location of a key hole and the selection of the proper key to lit a given lock.

'lhe second object is to so construct the device that it may be readily installed on any door without. necessitating the enercise of more than ordinary mechanical skill.,

'lhe third object is to so construct the device that ordinary flash light batteries can be employed to energize the lamp in the device.

The fourth object is to so construct the flash light that the batteries can easily be renewed by an inexperienced person without the use of tools.

'lhe fth object is to so construct the flash light that it. will accommodate itself to use in conjunction with a wide variety of door locks.

These and other objects will become more apparent from the specification following as illustrated in the accompanying drawing, in which:

Figure 1 is a front elevation showing the lock supporting portion of the door7 of which kFigure 2 is an end elevation. Figure 3 is a vertical section taken lalong the line 3-3 in Figure 4 Figure 4 is a vertical section taken through the device. Figure 5 is a horizontal section taken along the line 5-5 in Figure 4.

Similar numbers of reference refer to similar parts throughout the several views.

Referring in detail to the drawing, in order to illustrate the advantages of this device there is shown a type of door -11A having a lock 12A and plunger 13A and using only one knob 16A-on the inside of the door, while on the outside of the door is the pull handle 34, over which is placed a key hole into which is to be inserted a key 3G. For this type of door it is preferred to mortise into the woodwork of the door and insert a special casing 37 Whose flanged end 38 is secured to the door 11A by means of the screws 39.

0n the inside of the casing 37, and insulated therefrom, are the contact arms 40 and 41. The arm 41 engages the electrode 42 of the battery 43, and the arm 40 engages the bottom 44 of-the battery 45. Acontact clip 46 is secured to and insulated from the cover 47 whose spring catches 43 engage notches 49 on the inner walls of the casv ing 37.

rlhe flange 38 is preferably provided with the notched portions, 50 to facilitate the removal of the cover 47. 'llhe clip 46 makes the contact between the ends of the batteries 43 and 45. Between the arms 40 and 4l and the casing 37 is placed a strip of in sulation 51., Between the ends of themem bers 40 and 41 is also placed a piece of insulatlon 52, A clamping strip of insulation 53 is placed over the ends of the meinbers 40 and 41 andastrip of metal 54 is placed over the insulation 53,. 'lhe rivets 55 hold the arms 40 and 41. rigidly in place. lt will be understood that the arms 40 and 41 are insulated from each other and from the casing 37.

An opening 56 is formed in the door 11A in which is placed la shell 57 which is attached to the casing 37 by means of the screws 58., ln the shell 57 is secured a socket 59 for the lamp 60. A metallic button 61 also passes through the shell 57 and its end 62, which is provided with a spring 63, can pass through the casing 37 and make contact with the arm 41; whereas the contact point 64 of the lamp 60 passes through the casing 37 and is constantly in contact with the arm 40.

A hood 65 is placed over the button 61 and lamp v607 the former of which projects through the hood 65. rlhe hood 65 is secured to the door 111A by means of the screws 66.

lt will be observed that in order to adapt this form. of the device to right or left hand doors it is only necessary to remove the screws 58 and reverse the relation of the lamp and the button 61.

ln operation a pressure on the button 6l grounds the current from the batteries 43 and 45 through the lamps 40 and 41 through the button 61 and the lamp 60 by way of the shell 57, thereby energizing the lamp 60 and illuminating the key hole 35 or assisting in the finding of the proper key betere attempting to locate the key hole.

l am aware that dash lights of themselves are not new; l have therefore described a lOl) form of flash light especially designed to be permanently mounted on a door for the express purpose of assisting in the selection of the proper key to be used and` then in the location of the key'v hole in which said key is to be placed. I am also aware thatI there are a great many Ways in which this result can be obtained; I therefore do not intend to limit myself toy this precise form of construction, l do intend to cover all such forms and modifications as fall fairly Within the appended claim.

I claim:

A flash light for doors consisting of a battery; a casing for said battery adapted to which said battery can be replaced; and ahood in front of said lamp adapted to de'- lect the rays of light toward the key hole, said hood covering said shell and permitting said push button to project there,- through.
